Pukyong National University and joint research teams from Harvard and the University of Chicago have successfully developed an ultra-lightweight nanolattice structure-based flying device that can levitate using only sunlight. The novel nanostructure combines extremely low weight with high strength, enabling sustainable flight beyond the limits of conventional drones. This technology has the potential for applications in future environmental monitoring, space exploration, and communications infrastructure. The team maximized the mechanical properties of nanolattice design to allow flight with minimal solar energy. This breakthrough could revolutionize industrial platforms for long-term monitoring in harsh environments, fine dust and weather observation, and communication relay. The research has been published in a major international journal and is attracting global scientific interest. It also marks a significant step for Korea’s nanofabrication and advanced materials sectors in gaining international competitiveness.
